Summer of Ages couldn't have been better timed, as i had just got my maxed out oil wells before the five good emperors event started . In the last two weeks of the summer of ages , my oil production was nearing 300 oil per well per hour (1500/hour approx) . Thoroughly used the opportunity to take my second (often ignored ) factory from level 1 to level 6 over four weeks. Had some crowns saved so that helped in timely crowning. The other factory went from level 6 to level 7 (TH are awesome) . The second bunker (which was also ignored usually) went from level 2 to max atomic (still upgrading) . Apart from that i got the castle maxed and HTMK5 and strike fighter mk6 researches going. Oh man, the last three weeks were crazy oil grind, incessant tactics and training blessings and 4-6 hours of gameplay a day . But it was so totally worth it.
I was getting the feeling that nothing would motivate me to get my second factory to level 6 from level 1 , but the way summer of ages was structured, it was a perfect opportunity to take any building from ground zero to nearly max. It was an altogether different experience.
Second good thing was taking nearly 15 wall pieces (lvl 9) and 12 gates (lvl 12) to max atomic. The base looks whitey and beautiful (atleast some sections).
